Just watched an episode from 2019, youngish couple, two children, wanting to leave London, usual reasons, woman's parents also moving with them, therefore looking for house with annexe, budget £1.1m. First house, had a rundown garage at side of house which the presenter said could be converted for parents. Man had concerns 'not enough storage' not the fact that inlaws (who were probably contributing to house purchase) were going to live in converted garage! Just my thoughts.
